【０００１】
【発明の属する技術分野】
本発明は、人体や家畜をオゾンガスを用いて治療するオゾンガス医療に使用する医療用オゾンガス供給装置と該装置に使用するオゾンガス注射器接続用アダプタの構造に関するものである。
【０００２】
【従来の技術】
オゾンは、その高い酸化能のため、各種産業分野に使用されており、その用途は拡大の一途を辿っている。近年では、人体や家畜の医療用の分野への適用も始まっている。
【０００３】
オゾンを用いる各種治療法はドイツで開発され、その効果が認められて世界各地に普及しつつある。我が国においても「日本医療・環境オゾン研究会」が発足して急速に広まりつつある。例えば、家畜の医療用にオゾンガスを使用する例としては、牛の乳頭口から乳房内にオゾンガスを注入して牛の乳房炎の治療を行う方法がある（特許文献１及び特許文献２）。この方法は、酸素ボンベに接続したオゾンガス発生装置（オゾナイザー）でオゾンガスを生成させ、この生成したオゾンガスを含むオゾン・酸素混合ガスを、生成ガス誘導チューブの先端に配置されたオゾン注入管から牛の乳頭を通して乳房内に注入する方法である。使用するオゾン濃度は１〜５０ｍｇ／Ｌ（０．０５〜２．３％）とされている。
【０００４】
又、人を含む哺乳類の医療用にオゾンガスを使用する治療法としては、全身療法と局所療法とがあり、前者の代表的な療法としては自家血清療法がある。この自家血清療法は、患者の血液を５０〜１００ｍｌ抜き取り、これをバブリング等の方法でオゾンガスと接触させて改質し、これを通常の輸血の要領で体内に戻す方法であり、動脈硬化，Ｃ型肝炎，慢性間接リュウマチ炎或いはストレス性の疾患に効果があるとされている（特許文献３及び特許文献４）。その他、図９に示す如きオゾンガスノズル４０を直腸内に挿入しオゾンガス導管４１から供給されるオゾンガスを体内に注入したり、或いはオゾンガスを筋肉内に注射して、免疫全般の活性化を図る治療法もある。又、局所療法の代表例としては、１０〜５０ｍｌの低濃度オゾンガスを人体の皮下に注射する方法があり、肩凝り，しびれ或いは冷え性に効果があるとされている。その他、皮膚疾患療法として、図１０に示す様に、患部４６（図では下肢）を覆うオゾンバッグ４５内にオゾンガス導管４７からオゾンガスを供給し、オゾンの持つ高い殺菌作用により下肢潰瘍や皮膚病或いは真菌性感染症等の治療を行うものがある。又、直腸内に前記図９に示したオゾンガスノズル４０を用いてオゾンガスを注入する直腸炎や腸炎の治療法もある。この様に、オゾンガスを用いる各種治療法は急速に拡大しつつあるのが現状である。
【０００５】
尚、オゾンガスを、その使用場所（治療場所）へ供給する方法としては、該使用場所に放電式オゾナイザー等のオゾンガス発生装置を設置し、使用現場でオゾンガスを発生させる方法が一般的であるが、オゾナイザーで発生させたオゾンガスを、ボンベ内面のオゾンガスとの反応を抑止した構造のボンベにオゾンガスを加圧充填して貯蔵し、これを使用現場に移送して前記ボンベから必要量のオゾンガスを取り出して使用する方法もある（特許文献５参照）。

【０００７】
【発明が解決しようとする課題】
上記した従来のオゾンガスを用いる各種治療法において、オゾン源は放電式オゾナイザーの如きオゾンガス発生装置が使用されている。従って、このオゾナイザーを医療の現場に設置しなければならず、例えば、前述の牛の乳房炎の治療の場合には、牛舎にオゾナイザーを移送しなけばならないが、オゾナイザーを初めとする各種機器は、頻繁な移動を念頭においた設計にはなっていないので、移送中の振動等によりオゾナイザーや各種計器の故障の原因となる。又、係るオゾナイザーを稼働させるには、家庭用電源ではなく２００Ｖの工業用電力を必要とする場合もあり、又、放電による発熱を吸収するための水冷装置を具備しているのが一般的である。従って、牛舎等に２００Ｖの工業用電力を引き込んだり、水冷装置を稼働可能になす等の環境整備が必要となる。加えて、オゾナイザーには、高周波，高電圧が印加されるので、確実なアース対策等の十分な安全対策も必要である。
【０００８】
又、上記特許文献１及び２に記載の牛の乳房用オゾンガス注入装置では、オゾナイザーに接続された誘導チューブの先端にオゾンガス注入ノズルが接続されている構造であるので、牛に注入したオゾンガスの濃度や注入量を正確に測定する事は困難であった。
【０００９】
一方、人体にオゾンガスを注射したり、オゾンガス注入ノズルを用いて人体内にオゾンガスを注入する人のオゾンガス治療の場合には、病院の治療室にオゾナイザーを初めとする設備一式が設置されているので、移送によるトラブルの問題はないが、オゾナイザーが故障したり濃度異常が生じた場合に、その場での対応は不可能であった。
【００１０】
特に、オゾン医療がドイツで開発された関係上、現在日本で使用されているオゾ治療装置はドイツからの輸入品が多く、問題が生じても速やかな対応が困難であるという側面もある。
【００１１】
本発明は、係る医療の現場か抱える問題に鑑みてなされたものであって、トラブルが少なく、且つ安定した濃度のオゾンガスを医療現場に供給することを目的とするものである。
【００１２】
【課題を解決するための手段】
本発明は、上記目的を同時に達成するためになされたもので、その特徴とするところは、第１には、オゾナイザーに代えてオゾンガスを充填したボンベを使用する点であり、これによってオゾナイザーに起因する装置稼働上の問題や濃度の変動に対する問題を解消するものである。又、第２には、オゾンガス配管途上に注射器やオゾンガス注入ノズル等にオゾンガスを送給するためのオゾンガス取出手段を設けた点にあり、これによって定量のオゾンガスを容易にオゾンガス取出手段に供給する事ができる様にしたものである。
【００１３】
具体的には、第１の発明は、オゾンを内蔵したオゾンボンベと、該ボンベに接続された主配管系と、該主配管系の末端部に接続されたオゾン分解装置と、前記主配管系に配置された１以上のオゾンガス取出手段とを有してなる医療用オゾンガス供給装置にある。
【００１４】

【００１５】
又、システムとしては、前記主配管に、一端が酸素ボンベに接続された酸素配管を接続して、前記オゾンガスに酸素ガスを混合させてオゾンガスを酸素で希釈する様にしたものがある。これにより、酸素ガスによる希釈率を変化させる事によってオゾンガスの濃度を常に一定に保つ事が可能となる。特に、前記主配管系にオゾン濃度計を配置し、該オゾン濃度計にて検出されたオゾン濃度によって、前記オゾンボンベから供給されるオゾンガスと前記酸素ボンベから供給される酸素ガスとの混合比と混合量を調整して、該オゾンガスと酸素ガスとの混合ガスの流量とそのオゾン濃度が一定になる様に制御する自動制御手段を備えてなるものもある。この場合には、医療現場における医師による装置の運転制御が全く不要になり、医療現場での取扱いが極めて容易になる。
【００１６】
又、前記オゾンボンベについては、オゾンが加圧充填されており、自動的に放出される様になすのが好ましい。又、オゾンボンベを低温下で保存しておき、オゾンの自己分解を抑止する様にしてなるものが好ましい。
【００１７】
又、前記オゾンガス取出手段として、注射器にオゾンガスを注入するために配置される注射器装着用アダプタの構成としては、

前記本体シリンダ内に配置されたコイルバネ等の弾性部材によって前記注射器装着用開口部に向けて付勢され、該付勢力によって、前記前部小径部が前記注射器装着用開口部に突入して該注射器装着用開口部を閉塞し、
前記注射器の先端ノズル部が、前記弾性部材の付勢力に抗して前記注射器装着用開口部内に挿入されると、前記第１ガス通路及び第２ガス通路を通して前記注射器内にオゾンガスが注入される様に構成されているものである。
【００２０】
又、後者の可動弁部材の構成は、
前記本体シリンダの胴部内には、一端が該本体シリンダのオゾンガス流入側近傍に開口し他端が前記注射器装着用開口部の内壁部に開口するオゾンガス通路が形成されており、
前記可動弁部材は、前記注射器装着用開口部に挿入されて前記注射器装着用開口部を閉塞する前部小径部と該小径部に連接する後部大径部とからなり、且つ、前記本体シリンダ内に流入するオゾンガスの供給圧力によって前記注射器装着用開口部に向けて付勢され、該付勢力によって前記前部小径部が前記注射器装着用開口部に突入して該開口部が閉塞される様になっており、
前記注射器の先端ノズル部が、前記オゾンガスの供給圧力に抗して前記注射器装着用開口部内に挿入されると、前記オゾンガス通路を通して前記注射器内にオゾンガスが注入される様に構成されているものである。
【００２１】
又、前記注射器装着用アダプタの他の構成としては、前記オゾンガス注入支管の先端部に配置され且つ軟質弾性材で形成された閉塞部材と、該閉塞部材を前記オゾンガス注入支管の先端部に固定し且つ前面中央に開口部を有する押さえキャップと、からなるものであり、前記注射器の注射針を前記閉塞部材に突き刺して前記オゾンガス注入支管内のオゾンガスを前記注射器内に注入する様にしたものがある。
【００２２】
又、第２の発明は、前記オゾンガス注入支管に装着されて注射器にオゾンガスを注入するための注射器装着用アダプタの構造に関するものであり、後端部が前記支管に着脱自在に接続され先端部に注射器装着用開口部を有する本体シリンダと、前記注射器装着用開口部に配置された環状シール部材と、前記本体シリンダ内に配置されて、前記注射器を装着しないときは前記注射器装着用開口部内の前記環状シール部材内に前進突入して該開口部を閉塞し、前記注射器が装着されたときは該注射器に押されて後退し、前記注射器装着用開口部の閉塞を解除する可動弁部材と、からなるものである。
【００２３】
尚、前記可動弁部材の構成としては、前述の通り、コイルバネ等の弾性部材によって該弁部材で前記注射器装着用開口部を閉塞する構造のものと、オゾンガスのガス圧を利用して前記注射器装着用開口部を閉塞する構造のものとがある。
【００２４】
【発明の実施の形態】
以下に、図面の実施例を用いて本発明を詳細に説明する。先ず、図１は本発明に係る医療用オゾンガス供給装置の一例を示すフロー図であって、医療現場に配置される装置の構成機器を示している。同図において、オゾンガスを加圧貯蔵しているオゾンボンベ１から送出されたオゾンガスは、オゾンガス配管Ｌ１，酸素との混合配管Ｌ２，混合ガスの送給配管Ｌ３及び排出配管Ｌ４からなる主配管系Ｌ１〜Ｌ４を経て大気に放出される様になっている。即ち、前記オゾンボンベ１から供給されるオゾンガスは、オゾン配管Ｌ１，バルブＶ１，自動流量調整弁２ａ，酸素ガスとの混合配管Ｌ２，オゾン濃度計３，混合ガス送給配管Ｌ３及びバルブＶ２を経て、末端部に配置されたオゾン分解装置４に導入され、ここでオゾンガスは分解・無害化されて排出配管Ｌ４から大気中に放出される様になっている。前記混合ガス送給配管Ｌ３には、オゾンガス注入支管Ｌ５が分岐して設けられ、この先端部には、後述する本発明に係る注射器装着用アダプタ６が装着されている。又、同混合ガス配管Ｌ３には、オゾンガス供給支管Ｌ８が接続されており、バルブＶ５を開ければ、前記図９に示したオゾンガス注入ノズル４０や図１０に示したオゾンバッグ４５等の所定のオゾンガス治療器具にオゾンガスを供給する様になっている。更に、前記混合配管Ｌ２には、酸素ボンベ７に連結された酸素配管Ｌ６が接続されており、該配管Ｌ２において、オゾンガスと酸素ガスとが混合されて送給される様になっている。又、同配管Ｌ２には、真空ポンプ配管Ｌ７が接続され、該配管Ｌ７はバルブＶ３を介して真空ポンプ５に接続され、これによって、装置の主配管系内の残留ガスを真空ポンプ５を通して大気に排気する様になっている。
【００２５】
又、混合配管Ｌ２から供給されるオゾンガスの濃度は、オゾン濃度計３によって自動計測され、その計測信号が制御装置８に送信され、予め設定されている所定のオゾン濃度値と比較され、この比較信号に基づいて、前記オゾン配管Ｌ１に設けられている流量調節弁２ａ及び前記酸素配管Ｌ６に設けられている流量調節弁２ｂの弁開度が自動的に調整されて常に一定濃度のオゾンガスが一定量送給配管Ｌ３に供給される様になっている。尚、前記オゾン濃度計３は、単なるオゾン濃度センサーとしての機能を有するのみならず、測定されたオゾン濃度を数値で表示して使用者にオゾン濃度を明示する様になす事も可能である。
【００２６】
尚、オゾンボンベ１内には、オゾンガスが加圧下で希釈ガスである酸素ガスと共に充填されており、この保存中のオゾンの分解を抑止するために、ボンベ内表面が不動態化処理されているものが好ましく、具体的には、前記特許文献５に詳述されているものである。又、このオゾンボンベは、低温下で保管され、且つ使用時も低温に維持する方式のものが好ましい。
【００２７】
次に、図１に示した装置の使用方法（運転方法）について説明する。先ず、主配管系の残留ガスを排出する操作を行う。このため、前記オゾンボンベ１に接続されているオゾン配管Ｌ１のバルブＶ１と送給配管Ｌ３のバルブＶ２、酸素ボンベ７に接続されている酸素配管Ｌ６のバルブＶ４及びオゾンガス供給支管Ｌ８のバルブＶ５を閉じ、真空ポンプ配管Ｌ７のバルブＶ３を開けて真空ポンプ５を作動させる。これにより、バルブＶ１からバルブＶ２及びバルブＶ５間の配管内の残留ガス、及び後述するオゾンガス注入配管Ｌ５とこれに接続されている注射器装着用アダプタ６内に残留しているガス、並びに酸素配管Ｌ６のバルブＶ４以降の配管内に残留しているガスを前記真空ポンプ５を通して排気する。所定の排気が完了すると前記バルブＶ３を閉じて真空ポンプ５を停止すると、配管内は所定の真空状態となる。
【００２８】
配管系の排気操作が完了すると、続いて配管系への新ガス供給操作を行う。即ち、前記配管系が所定の真空に至った状態において、前記オゾンボンベ１のバルブＶ１及び酸素ボンベ７のバルブＶ４を開くと、夫々のボンベ１，７からオゾンガス及び酸素ガスが夫々配管Ｌ１及び配管Ｌ６を経て配管Ｌ２，Ｌ３，Ｌ５，Ｌ８内に流入して充満する。続いて、送給配管Ｌ３のバルブＶ２を開くと、オゾンガスと酸素との混合ガスは、オゾン分解装置４を経て排出配管Ｌ４から分解ガス（酸素主体のガス）として大気中に放出される。
【００２９】
この状態においては、必ずしも前記送給配管Ｌ３に送給されるオゾンガス濃度や流量は所定の値に達していない。即ち、後述する様に、オゾンボンベ１内のオゾンは、時間の経過と共に自已分解して濃度低下を生じるので、新しいボンベ装着時のオゾン濃度と、数週間経過後のオゾン濃度とは多少異なったものとなっており、これを一定濃度に調整して送給する必要がある。そこで本発明装置においては、前記濃度計３でオゾン濃度を検出し、オゾン濃度が低下しておれば、希釈ガスとしての酸素ガス量を減少させる様に前記酸素配管Ｌ６の流量調整弁２ｂの開度を下げて酸素ガス流量を低減させると共に、その低減させた酸素量に相当する量のオゾンガス流量を増加させるべく前記オゾン配管Ｌ１の流量調節弁２ａの開度を上げる操作を行う。この操作を、前記制御装置８の指示によって微分的に行う事により、送給配管Ｌ３に供給される混合ガス中のオゾン濃度を一定となすと同時に流量も一定となす様に制御される。この自動制御操作により、送給配管Ｌ３内には、短時間で、一定流量で且つ一定濃度のオゾンガスが流通している状態になる。同時に、前記送給配管Ｌ３に接続されているオゾンガス供給支管Ｌ８及びオゾンガス注入支管Ｌ５並びに該オゾンガス注入支管Ｌ５に接続されている注射器装着用アダプタ６内にも所定濃度のオゾンガスが充満する事になるので、前記オゾンガス供給支管Ｌ８からオゾンガスを治療器具に供給してオゾンガス治療を開始したり、或いは、前記注射器装着用アダプタ６に注射器を装着して後述する要領によりオゾンガスを注射器内に注入するする操作を行う。
【００３０】
先ず、オゾンガス供給支管Ｌ８からオゾンガスを供給する治療について説明する。前述の操作により、オゾン濃度計３の表示濃度が所定のオゾン濃度に達すると、オゾンガス供給支管Ｌ８のバルブＶ５を開け、バルブＶ２を閉じて所定濃度のオゾンガスを一定流量で、該オゾンガス供給支管Ｌ８からオゾンガス治療器具に供給する。オゾンガス治療器具が図９に示したオゾンガス注入ノズル４０の場合には、該オゾンガス注入ノズル４０に連結されているオゾンガス導管４１が前記オゾンガス供給支管Ｌ８と連結されている。従って、前記オゾンガス供給支管Ｌ８から供給されてくるオゾンガスは、オゾンガス導管４１を経て、体内に挿入されているオゾンガス注入ノズル４０に供給され、該ノズルに設けられた複数のガス噴出孔４２から体内に噴出して所定の作用を人体に及ぼす事によって治療が行われる事になる。
【００３１】
又、前記オゾンガス治療器具が図１０に示したオゾンバッグ４５の場合には、該オゾンガスバッグ４５に連結されているオゾンガス導管４７が前記オゾンガス供給支管Ｌ８と連結されている。従って、前記オゾンガス供給支管Ｌ８から供給されてくるオゾンガスは、オゾンガス導管４７を経て前記オゾンバッグ４５内に供給され、人体の患部（図では下肢）に生じている感染症や皮膚病等の治療が行われる事になる。尚、前記オゾンバッグ４５は、密閉した樹脂フィルム製のバッグでも良いが、該バッグに微小の孔が複数形成しておき、オゾンの分解物である酸素ガスを少量づつ放出しつつ新鮮なオゾンガスが該オゾンバッグ４５内に連続供給される様になすのが好ましい。
【００３２】
次に、オゾンガス注入支管Ｌ５に設けられた前記注射器装着用アダプタ６（以下単に『アダプタ』と記載する）を通して、注射器にオゾンガスを注入する操作について説明する。図２〜図４は、このアダプタの第１実施例を示す断面図であり、図２は、装置の停止状態及び前記真空ポンプ５による配管内の真空脱気状態におけるアダプタの内部状態を示し、図３は、真空脱気後のオゾンガスが配管内に充満している状態のアダプタの内部状態を示し、図４は、該アダプタに注射器を装着してオゾンガスを該注射器に注入するオゾンガス注入工程に於ける該アダプタと注射器の関連を示す断面図である。
【００３３】
先ず、図２において、アダプタ６は、本体シリンダ１０と、内部に圧縮コイルバネ等の弾性部材１２よって前方に付勢されている可動弁部材１１とから構成され、前記本体シリンダ１０の先端部には注射器装着用開口部１０ｃが形成され、後端部には、前記オゾンガス注入配管Ｌ５の先端に装着される螺合部１０ｄを有しており、該螺合部１０ｄによって前記オゾンガス注入支管Ｌ５に対して着脱自在となっている。又、前記注射器装着用開孔１０ｃの内面には、Ｏリング等の環状シール部材１６が配置されている。
【００３４】
前記可動弁部材１１は、後側（図面の上側）の大径部１１ａと、これに連接して一体的に形成された前側（図面の下側）の小径部１１ｂとからなり、大径部１１ａの後面が前記圧縮コイルバネ１２によって押圧されて、常時前方に付勢されている。又、装置が運転されていない状態では、前記本体シリンダ１０の先端部に形成されている注射器装着用開口部１０ｃ内に閉塞プラグ１７が挿入され、該プラグ１７の外周面と前記環状シール部材１６とが密に接する事によって、アダプタ６内部は大気とは気密に保持されている。
【００３５】
又、前記後側大径部１１ａには、軸方向に貫通する第１ガス通路１３が形成され、前記前側小径部１１ｂには、周方向から軸心に向かって穿孔された横孔１４ａとこれに連通して先端部に開孔する様に穿孔された縦孔１４ｂとからなる第２ガス通路１４が形成されており、これら第１，第２のガス通路は、後述する様にオゾンガスの通路となるものである。装置が稼働していない状態では、前記閉塞プラグ１７が前記注射器装着用開口部１０ｃ内に挿入されているので、前記可動弁部材１１の前記小径部１１ｂの先端は該閉塞プラグによって前進が阻まれ、前記第２ガス通路１４は、本体シリンダ１０内に連通した状態となっている。
【００３６】
この状態で、前述した真空ポンプ５による配管内の脱気操作を開始すると、前記本体シリンダ１０内の後部空間１０ａ内に残留している空気や、前回の使用時に用いた酸素ガス等が配管Ｌ３を通して脱気され、又、該本体シリンダ１０の前部空間１０ｂ内の残留気体は、前記第１ガス通路１３を通して排気される。尚、前記注射器装着用開口部１０ｃは、前記環状シール部材１６と閉塞プラグ１７とによって気密にシールされているので、外気が該開口部１０ｃを通して流入するのは阻止されている。
【００３７】
次に、オゾンボンベ１からオゾンガスが配管系に供給され、配管系内にオゾンガスが充満されると、図３に示している様に前記閉塞プラグ１７を抜き取る。すると、前記弾性部材１２の付勢力により、前記可動弁部材１１は前方に押されて移動し、前記前側小径部１１ｂは前記注射器装着用開口部１０ｃ内に突入して前記環状シール部材１６によって第２ガス通路１４が閉塞され、前記本体シリンダ１０内と外気とは依然として気密状態に保持されている。
【００３８】
次に、図４に示す如く、この状態で注射器１５の先端ノズル部１５ｃを、前記弾性部材１２の付勢力に抗して前記注射器装着用開口部１０ｃに挿入すると、前記可動弁部材１１は後退し、前記オゾンガス注入支管Ｌ５及び送給配管Ｌ３と注射器１５とが連通される。この状態で該注射器１５のピストン１５ｂを後退させると、オゾンガスは、前記本体シリンダ１０の後部空間１０ａ，前記可動弁部材１１の大径部１１ａに形成された第１ガス通路１３，本体シリンダの前部空間１０ｂ及び前記可動弁部材の小径部１１ｂに形成された第２ガス通路１４を経て、先端ノズル部１５ｃから注射器１５のシリンダ１５ａ内に注入される事になる。尚、オゾンガスの圧力を適度に設定し、前記注射器１５の先端ノズル１５ｃを前記開口部１０ｃに挿入するだけでオゾンガスの圧力によって自動的にオゾンガスが注射器内に流入する様になす事も可能である。所定量のオゾンガスが該注射器１５内に注入され、該注射器１５をアダプタ６から抜き取ると、前記可動弁部材１１は、再度前記弾性部材１２に押されて前方に移動し、前述の図３の状態に戻って、アダプタ内のオゾンガスは外部に漏出する事はない。
【００３９】
尚、最初に注射器１５に注入されたオゾンガスは、真空脱気直後に供給された濃度未調整のオゾンガスが混入している可能性もあるので、初回の注入分は放出し、再度、注射器を挿入してオゾンガスの注入を行う事も可能である。又、この間もオゾンガスは配管内を流通しているので、注射器に注入されない残部のオゾンガスは、前記オゾン分解装置４で分解無害化されて排出配管Ｌ４から大気中に放出される事は前述の通りである。
【００４０】
上記実施例において、弾性部材としては圧縮コイルバネを図示しているが、本発明は、これに限定されるものではなく、板バネや空気バネ等も使用可能である事はいうまでもない。又、前記環状シール部材１６も、Ｏリングの例を図示しているが、これに限定されるものではなく、軟質ＶパッキンやＵパッキンも使用可能であり、これらＶパッキンやＵパッキンを使用する場合には、この配置方向を内外からのシールが行える様に逆向きに配置した多段シール構造となすのが好ましいシール構造と言える。
【００４１】
次に、図５〜図７は、アダプタの第２実施例を示す断面図であり、第１実施例においては、前記可動弁部材１１が、圧縮バネ等の弾性部材で前方に付勢される様にしているが、この第２実施例では、オゾンガスの供給ガス圧を利用して該弁部材を可動にしたものである。図５〜図７は、前記図２〜図４に対応する断面図であって、図５は、装置の停止状態及び前記真空ポンプ５による配管内の真空脱気状態におけるアダプタの内部状態を示し、図６は、真空脱気後のオゾンガスが配管系内に充満している状態のアダプタの内部状態を示し、図７は、該アダプタに注射器を装着してオゾンガスを該注射器に注入するオゾンガス注入工程に於ける該アダプタと注射器の関連を示す断面図である。
【００４２】
先ず、図５において、アダプタ６は、本体シリンダ１０と内部に可動に配置された可動弁部材１１とを有する点では前記第１実施例と同一であるが、本例では前記本体シリンダ１０の胴部内に、一端がオゾンガスの流入側近傍に開口し他端が前記注射器装着用開口部１０ｃの内壁面に開口するオゾンガス通路２０が形成されており、本体シリンダ１０内の前部空間１０ｂは、連通孔２２を介して大気と連通した構造となっている。尚、第１実施例と同一構成は同一符号を付して重複説明は省略する。
【００４３】
前記可動弁部材１１は、後側（図面の上側）の大径部１１ａと、これに連接して一体的に形成された前側（図面の下側）の小径部１１ｂとからなる点は前記第１実施例のものと同一であるが、本例では、大径部１１ａの外周面にＯリング２１が配置されており、これによって、本体シリンダ１０内を、後部空間１０ａと前部空間１０ｂとに画成すると共に、両空間の間を気密に形成している。又、前記注射器装着用開口部１０ｃの後端側には、前記小径部１１ｂと接してシールするＯリング２３が配置されている。装置が運転されていない状態では、前記注射器装着用開口部１０ｃ内に閉塞プラグ１７が挿入され、該注射器装着用開口部１０ｃは大気に気密に保持されている。
【００４４】
この状態で、前述した真空ポンプ５による配管内の脱気操作を開始すると、前記本体シリンダ１０内の後部空間１０ａ及び前記ガス通路２０内に残留している空気や前回の使用時に用いた酸素ガス等は、前記オゾンガス注入支管Ｌ５及び送給配管Ｌ３を通して脱気され、前記本体シリンダ１０の前部空間１０ｂ内には、該シリンダ１０の胴部を貫通して大気と連通させる連通孔２２から大気が流入するので、前記可動弁部材１１の後部空間１０ａは真空状態となるが反対側の前部空間１０ｂは大気圧に維持される結果、該可動弁部材１１は図中上方に向かって最上端まで移動して押圧された状態となる。この状態では、前記オゾンガス通路２０のいずれの開口も、本体シリンダ１０の前部空間１０ｂには連通しない様に前記ガス通路２０の開口位置が決定されている。
【００４５】
次に、前記オゾンボンベ１及び酸素ボンベ７からオゾンガス及び酸素ガスが配管内に供給され、配管内にオゾンガスが充満された後に、前記閉塞プラグ１７を抜き取ると、オゾンガスの供給圧力は大気圧以上であるから、図６に示している様に、前記可動弁部材１１はオゾンガスの圧力に押されて最前端部（図中最下端部）まで移動し、前記可動弁部材１１の小径部１１ｂの先端部は、前記環状シール部材１６内に突入する。この状態では、前記小径部１１ｂの下端部が前記環状シール部材１６と接してシールし、上端部は前記開孔部１０ｃの内部に配置されたＯリング２３によってシールされているので、オゾンガスは、本体シリンダ１０の後部空間１０ａからオゾンガス通路２０内に流入してくるが、前記両シール部材１６，２３間に前記オゾンガス通路２０が開口する様に構成されているのでオゾンガスが外部に漏れだす事はない。
【００４６】
次に、図７に示す如く、この状態で注射器１５の先端ノズル部１５ｃを、前記オゾンガスの圧力に抗して前記注射器装着用開口部１０ｃに挿入すると、前記可動弁部材１１は後退し、オゾンガス注入配管Ｌ５と注射器１５とが、前記後部空間１０ａとオゾンガス通路２０を介して連通される。この状態で該注射器１５のピストン１５ｂを後退させると、オゾンガスは、前記本体シリンダ１０の後部空間１０ａ及び前記オゾンガス通路２０を経て、先端ノズル部１５ｃから注射器１５のシリンダ１５ａ内に注入される事になる。所定量のオゾンガスが該注射器１５内に注入され、該注射器１５をアダプタ６から抜き取ると、前記可動弁部材１１は、再度オゾンガスのガス圧に押されて前方に移動し、前述の図６の状態に戻り、オゾンガスは外部に漏れる事なくシールされる事になる。
【００４７】
次に、図８は、本発明に使用する注射器接続用アダプタ６の他の実施例を示す要部断面図である。本例は、最も単純な構造のものであり、前記オゾンガス注入支管Ｌ５の先端部３３に接する様に、シリコンゴム等の軟質弾性材料で形成した閉塞部材３０を配置し、その外側から該閉塞部材３０の周縁部を押え部３４で囲繞して押圧する固定キャップ３１を装着したものであり、該固定キャップ３１は前記オゾンガス注入支管Ｌ５の先端外周部に螺合して固着される様に構成されている。尚、前記固定キャップ３１の中央部には開口部３２が形成されており、前記閉塞部材３０は該開口部３２の部分で露出している。前述の如く前記配管系が真空に脱気される際には、該閉塞部材３０によって配管内は外気と遮断されているので、外気が配管内に流入する事はない。配管内に所定のオゾンガスが供給されると、注射器１５の注射針１８を前記閉塞部材３０に差し込んで、その先端部を前記支管Ｌ５内に露出させ、この状態で注射器のピストン１５ｂを後退させてオゾンガスを注射器１５内に吸引注入する。所定量のオゾンガスが注入されると前記注射針１８を前記閉塞部材３０から引き抜き、そのまま、或いは、極細の注射針に取り替えて患者の所定部に注射する事になる。
【００４８】
この実施例においては、前記閉塞部材３０はシリコンゴム等の軟質弾性材で形成されているので、注射針１８を容易に差し込む事ができ、又、該注射針１８を引き抜いた後の前記閉塞部材３０に形成された貫通孔は、該閉塞部材３０が軟質弾性材で形成されているので、自閉作用によって閉塞され、配管内部のオゾンガスが外部に流出したり、外気が配管内に流入する事はない。但し、繰り返し使用されると、注射針によって形成された貫通孔が連結して次第に大きな孔が形成されると共に、前記軟質弾性材自体も劣化が進行するので、適当な期間毎に取り替える事は言うまでもない。又、その取り替えも極めて容易である事は、図面からも容易に理解されよう。
【００４９】
以上の説明においては、オゾンガス注入支管Ｌ５とオゾンガス供給支管Ｌ８とを各１つづつ主配管に配置しているが、これは、いずれか一方のみでも或いはいずれかを複数配置したり両方を複数配置する事も可能である。又、これらの主配管系上の配置位置についても、オゾン濃度計３の下流側に設けた例を示しているが、この位置も、酸素ガス配管Ｌ６が混合配管Ｌ２で合流する場所の下流側であって前記オゾン分解装置４の上流側であれば、その取付け位置は任意である。
【００５０】
又、図１の例では、真空ポンプ５により、配管内の脱気が行える様にしているが、これは、主として、長期間装置の運転を行わずに放置していた様な場合に、配管内に残留していたオゾンガスが酸素に分解され、酸素ガスとして滞留していたり、或いは、装置のメンテナンス等（例えば、オゾンボンベや酸素ボンベの交換や配管継ぎ手のパッキンの交換等）の際に配管中に流入する空気を、装置運転開始後のオゾンガスによるパージ作業（配管中の残留ガスを所定のオゾンガスに置換する作業）を短縮するために行うものであるので、この真空ポンプ５は必ずしも必須ではなく省略する事も可能である。
【００５１】
更に、図１の例では、酸素ボンベ７から供給される酸素ガスによってオゾンガスを希釈する例を示しているが、前記図１０に示した皮膚病等の治療用のオゾンガスの場合には、体内に注入されるオゾンガスと違って、オゾンガスの濃度管理には厳密性がさほど要求されないので、酸素ガスによる希釈とこれによる濃度管理を行う事なく、オゾンボンベ１のみを用いる方式も可能であるが、多目的の医療用オゾンガス供給装置とするためには、図１に示した如く、酸素ガスによる希釈とオゾン濃度計３及び制御装置８等による濃度と流量の管理が行える様になすのが好ましい事はいうまでもない。
【００５２】
上述の通り、本発明は、従来のオゾナイザーに代わってオゾンガスを吸着剤に吸着保持させたオゾンボンベを使用するものであるので、オゾンボンベにおけるオゾンガスの長期保存性が要求される。そこで、オゾンボンベによる減衰試験を行ったので、以下にその試験内容と結果を示す。
【００５３】
〔試験例１〕
容量１０Ｌ（リットル）のオゾンボンベにオゾンガスを０．９ＭＰａで充填した後、室温（２５℃）に放置したときのオゾン濃度の変化を測定した。その結果を表１に示す。
【００５４】

【００５５】
人体に注射する場合のオゾン濃度は２０μｇ／ｍｌ（約０．９３ｖｏｌ．％）が基本となるので、上記試験例からも明らかな様に、常温でオゾンボンベを保存していても、１月以上の保存は全く問題のない事が分かる。又、前述の牛の乳房炎の治療用のオゾン濃度は、前記特許文献２には１〜５０ｍｇ／リットル（０．０５〜２．３％）が好ましいと記載されており、本発明で使用するオゾンボンベは、係る牛の乳房炎の治療にも十分使用可能である事が理解されよう。
【００５６】
〔試験例２〕
前記オゾンボンベは低温保存するのが好ましい。そこで、上記試験例１に用いたのと同一の容量１０Ｌのオゾンボンベにオゾンガスを０．９ＭＰａで充填し、これを４℃に保持したときのオゾン濃度の変化を測定した。その結果を表２に示す。
【００５７】

【００５８】
上記試験例２からも明らかな通り、４℃で保存すると、４週間後におけるオゾン濃度の減衰率は僅か４％弱であり、常温保存の場合の試験例１における減衰率（２０％弱）に比べて著しく低い事が分かる。この意味からも、オゾンボンベは低温で保存するのが好ましいと言える。この保存方法は、オゾンボンベの使用頻度にも依る事はいうまでもなく、１〜２週間程度でボンベ内のオゾンガスを使い切る様な場合には、常温保存でも低温保存でも大差はないといえるが、使用頻度が低い場合には、低温保存が推奨される。尚、オゾンボンベを低温保存する方法としては、冷蔵庫に保管する方法もあるが、頻繁に本装置を使用する様な場合には、ペルチェ素子を用いた専用冷却容器内に該オゾンボンベを配置しておくのが簡便で好ましい方策である。
【００５９】
以上説明した通り、本発明では、オゾンガス源として従来のオゾナイザーに替えてオゾンボンベを使用し、同時に、オゾンガス配管に、注射器にオゾンガスを注入するアダプタや、オゾンバッグ或いはオゾンガス注入ノズル等のオゾンガス治療器具にオゾンガスを供給するオゾンガス供給支管を設けたものであり、オゾンガス治療器具としては、現在も種々のものが使用されているので、本発明は、上記実施例に示したオゾンバッグやオゾンガス注入ノズル用の医療用オゾンガス供給装置に限定されるものではなく、特許請求の範囲に記載の発明思想に徴して種々のバリエショーンが存在するものである事は言うまでもない。又、注射器装着用のアダプタの構造も、上記実施例に示したものの他、種々の形式の変形例が存在するものであって、本発明が上記実施例に限定されるものではない。
【００６０】
【発明の効果】
以上に詳述した如く、本発明のオゾンガス注入装置によると、第１には、オゾンガス供給源として、従来のオゾナイザーに代えてオゾンボンベを使用しているので、従来の様に治療場所にオゾナイザーを搬送する必要がなく、装置の故障等の搬送に起因するトラブルを排除する事が可能となる。
【００６１】
又、現場で治療に従事する医者にとっては、オゾナイザーのメンテナンスは困難であり、一旦故障するとオゾン治療を中断せざるを得ず、患者に対する配慮に欠けたシステムであったが、本発明では、オゾナイザーを使用せず、通常の医療現場でも使用されている酸素ボンベや窒素ボンベの如く、ボンベ内のガスの残量管理だけで良くなるので、医療現場におけるトラブルの発生を大幅に抑制する事が可能となり、医者にとっても患者にとっても信頼できる装置となる。
【００６２】
又、オゾンガスを注射器に注入して使用する場合には、注射器を装着するためのアダプタをオゾンガス配管に取り付けており、しかも、オゾンガスの注入操作としては、注射器の先端ノズルを該アダプタに挿入するだけで、或いは、従来一般に医療現場で行われている様に薬瓶に注射針を挿入して薬液を吸引する要領でオゾンガス配管に設けられた注射針の差し込み口に注射針を差し込むだけで、自動的に或いは手動により注射器のピストンを引き上げる事により、所定量のオゾンガスを注入する事が可能となるので、オゾンガスの注射器への注入操作も極めて簡単に行う事ができる。
【００６３】
更に、前記アダプタは、簡単にオゾンガス配管に取り付ける事が可能であり、且つ簡単な構造であるので故障する事もなく、長期に亘って安定して使用する事が可能となる。
【００６４】
又、オゾンガス流量とオゾンガス濃度は、常に一定に保持される構造のものを採用すれば、常に安定した量のオゾンを患部に注射する事ができるので、医者によっては治療計画が立て易くなり、従来の装置におけるオゾン濃度不明の状態が解消され、医者や患者にとっても、治療効果の確認が容易となる。
【００６５】
又、オゾンバッグやオゾンガス注入ノズルを用いる治療法においても、オゾンガスが容易且つ安定して供給される様になるので、オゾンガス治療の一層の普及が進展し、多くの医療機関において容易にオゾン治療を受ける事が可能となり、国民の健康維持と増進に大きく貢献する事が期待される。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a medical ozone gas supply device used for ozone gas medical treatment for treating a human body or livestock using ozone gas, and an ozone gas syringe connection adapter used for the device.
[0002]
[Prior art]
Ozone is used in various industrial fields because of its high oxidizing ability, and its use is continually expanding. In recent years, application to the medical field of the human body and livestock has begun.
[0003]
Various treatments using ozone have been developed in Germany, and their effects have been recognized and are spreading around the world. In Japan, the “Japan Society for Medical and Environmental Ozone Study” has been established and is spreading rapidly. For example, as an example of using ozone gas for medical treatment of livestock, there is a method of treating mastitis in cattle by injecting ozone gas into the breast from the teat opening of cattle (Patent Documents 1 and 2). According to this method, ozone gas is generated by an ozone gas generator (ozonizer) connected to an oxygen cylinder, and an ozone / oxygen mixed gas containing the generated ozone gas is supplied from an ozone injection pipe disposed at the tip of a generated gas guide tube. It is a method of injecting into the breast through the nipple. The concentration of ozone used is 1 to 50 mg / L (0.05 to 2.3%).
[0004]
Treatment using ozone gas for medical treatment of mammals including humans includes systemic treatment and local treatment, and the former typical treatment includes autologous serum treatment. In this autoserum therapy, 50 to 100 ml of a patient's blood is withdrawn, contacted with ozone gas by a method such as bubbling, reformed, and returned to the body in the manner of normal blood transfusion. It is said to be effective against hepatitis C, chronic indirect rheumatitis or stress-related diseases (Patent Documents 3 and 4). In addition, an ozone gas nozzle 40 as shown in FIG. 9 is inserted into the rectum to inject ozone gas supplied from an ozone gas conduit 41 into the body, or ozone gas is injected intramuscularly to activate the whole immunity. There is also. As a typical example of the topical therapy, there is a method of injecting 10 to 50 ml of low-concentration ozone gas under the skin of a human body, which is said to be effective for stiff neck, numbness or coldness. In addition, as a skin disease therapy, as shown in FIG. 10, ozone gas is supplied from an ozone gas conduit 47 into an ozone bag 45 that covers an affected part 46 (lower limb in the figure), and lower limb ulcer, skin disease or There are treatments for fungal infections and the like. There is also a method for treating proctitis or enteritis by injecting ozone gas into the rectum using the ozone gas nozzle 40 shown in FIG. Thus, at present, various treatment methods using ozone gas are rapidly expanding.
[0005]
As a method of supplying ozone gas to a place of use (treatment place), a method of installing an ozone gas generator such as a discharge-type ozonizer at the place of use and generating ozone gas at the place of use is common. The ozone gas generated by the ozonizer is stored in a cylinder having a structure in which the reaction with the ozone gas on the inner surface of the cylinder is suppressed by pressurizing and storing the ozone gas, and the necessary amount of ozone gas is taken out from the cylinder by transferring it to the use site. There is also a method used (see Patent Document 5).

[Problems to be solved by the invention]
In the above-mentioned various treatment methods using ozone gas, an ozone gas generator such as a discharge ozonizer is used as an ozone source. Therefore, this ozonizer must be installed at a medical site.For example, in the case of the above-mentioned treatment for mastitis of cattle, the ozonizer must be transported to a barn. However, since the design is not designed with frequent movements in mind, vibrations during transportation may cause a failure of the ozonizer and various instruments. In order to operate such an ozonizer, industrial power of 200 V may be required instead of a household power supply, and a water cooling device for absorbing heat generated by discharge is generally provided. is there. Therefore, it is necessary to improve the environment such as drawing 200 V of industrial electric power into a barn or the like, and enabling a water cooling device to operate. In addition, since high frequency and high voltage are applied to the ozonizer, sufficient safety measures such as reliable grounding measures are also required.
[0008]
In addition, the ozone gas injection apparatus for cow's breast described in Patent Documents 1 and 2 has a structure in which an ozone gas injection nozzle is connected to the tip of an induction tube connected to an ozonizer. And it was difficult to measure the injection amount accurately.
[0009]
On the other hand, in the case of ozone gas therapy for a person who injects ozone gas into the human body or injects ozone gas into the human body using an ozone gas injection nozzle, a set of equipment including an ozonizer is installed in the treatment room of the hospital. Although there was no problem of transfer, there was no immediate response when the ozonizer broke down or an abnormal concentration occurred.
[0010]
In particular, because ozone medicine was developed in Germany, many ozone treatment devices currently used in Japan are imported from Germany, and it is difficult to respond quickly even if problems arise.
[0011]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the embodiments of the drawings. First, FIG. 1 is a flowchart showing an example of a medical ozone gas supply device according to the present invention, and shows components of the device disposed at a medical site. In the figure, the ozone gas delivered from an ozone cylinder 1 storing ozone gas under pressure is supplied to an ozone gas pipe L1, a mixing pipe L2 with oxygen, a mixed gas supply pipe L3, and a discharge pipe L4 composed of a main pipe system L1. Through L4 to the atmosphere. That is, the ozone gas supplied from the ozone cylinder 1 passes through an ozone pipe L1, a valve V1, an automatic flow control valve 2a, a mixing pipe L2 with oxygen gas, an ozone concentration meter 3, a mixed gas supply pipe L3, and a valve V2. The ozone gas is introduced into an ozone decomposing device 4 disposed at the terminal end, where the ozone gas is decomposed and made harmless and discharged into the atmosphere from a discharge pipe L4. An ozone gas injection branch pipe L5 is provided in a branched manner in the mixed gas supply pipe L3, and a syringe mounting adapter 6 according to the present invention, which will be described later, is mounted at a distal end of the branch pipe. An ozone gas supply branch pipe L8 is connected to the mixed gas pipe L3. When the valve V5 is opened, a predetermined ozone gas such as the ozone gas injection nozzle 40 shown in FIG. 9 or the ozone bag 45 shown in FIG. Ozone gas is supplied to the treatment device. Further, an oxygen pipe L6 connected to the oxygen cylinder 7 is connected to the mixing pipe L2. In the pipe L2, an ozone gas and an oxygen gas are mixed and supplied. Further, a vacuum pump pipe L7 is connected to the pipe L2, and the pipe L7 is connected to the vacuum pump 5 via a valve V3, whereby residual gas in the main pipe system of the apparatus is passed through the vacuum pump 5 to the atmosphere. To be exhausted.
[0025]
Further, the concentration of the ozone gas supplied from the mixing pipe L2 is automatically measured by the ozone concentration meter 3, a measurement signal is transmitted to the control device 8, and is compared with a predetermined ozone concentration value set in advance. Based on the signal, the valve opening of the flow rate control valve 2a provided in the ozone pipe L1 and the flow rate control valve 2b provided in the oxygen pipe L6 are automatically adjusted, so that the ozone gas having a constant concentration is always constant. It is designed to be supplied to the quantity supply pipe L3. The ozone concentration meter 3 can not only have a function as a simple ozone concentration sensor, but also can display the measured ozone concentration in a numerical value to clearly show the ozone concentration to the user.
[0026]
The ozone cylinder 1 is filled with ozone gas under pressure and oxygen gas, which is a diluent gas, and the inner surface of the cylinder is passivated in order to suppress the decomposition of ozone during storage. These are preferred, and specifically, those described in detail in Patent Document 5 mentioned above. It is preferable that the ozone cylinder be stored at a low temperature and be maintained at a low temperature during use.
[0027]
Next, how to use (operate) the device shown in FIG. 1 will be described. First, an operation of discharging the residual gas in the main piping system is performed. Therefore, the valve V1 of the ozone pipe L1 and the valve V2 of the supply pipe L3 connected to the ozone cylinder 1, the valve V4 of the oxygen pipe L6 connected to the oxygen cylinder 7, and the valve V5 of the ozone gas supply branch pipe L8 are connected. Close and open the valve V3 of the vacuum pump pipe L7 to operate the vacuum pump 5. Thereby, the residual gas in the pipe between the valve V1 and the valve V2 and the valve V5, the gas remaining in the ozone gas injection pipe L5 described later and the syringe mounting adapter 6 connected thereto, and the oxygen pipe L6 The gas remaining in the piping after the valve V4 is exhausted through the vacuum pump 5. When the predetermined evacuation is completed, when the valve V3 is closed and the vacuum pump 5 is stopped, the inside of the pipe is brought into a predetermined vacuum state.
[0028]
When the exhaust operation of the piping system is completed, a new gas supply operation to the piping system is subsequently performed. That is, when the valve V1 of the ozone cylinder 1 and the valve V4 of the oxygen cylinder 7 are opened in a state where the piping system has reached a predetermined vacuum, ozone gas and oxygen gas are respectively supplied from the cylinders 1 and 7 to the pipe L1 and the piping L1, respectively. After flowing through L6, it flows into the pipes L2, L3, L5 and L8 to be filled. Subsequently, when the valve V2 of the supply pipe L3 is opened, the mixed gas of ozone gas and oxygen is discharged to the atmosphere as a decomposition gas (a gas mainly composed of oxygen) from the discharge pipe L4 via the ozone decomposition device 4.
[0029]
In this state, the concentration and the flow rate of the ozone gas supplied to the supply pipe L3 do not necessarily reach predetermined values. That is, as described later, the concentration of ozone in the ozone cylinder 1 is reduced by self-decomposition over time, and the ozone concentration when a new cylinder is installed is slightly different from the ozone concentration after several weeks. It is necessary to adjust this to a certain concentration before sending. Therefore, in the apparatus of the present invention, the ozone concentration is detected by the concentration meter 3, and if the ozone concentration is reduced, the flow control valve 2b of the oxygen pipe L6 is opened so as to reduce the amount of oxygen gas as a dilution gas. In addition to reducing the oxygen gas flow rate by decreasing the degree, the operation of increasing the opening degree of the flow control valve 2a of the ozone pipe L1 is performed to increase the ozone gas flow rate corresponding to the reduced oxygen amount. By performing this operation differentially in accordance with the instruction of the control device 8, control is performed so that the ozone concentration in the mixed gas supplied to the feed pipe L3 is constant and the flow rate is also constant. By this automatic control operation, a state in which ozone gas having a constant flow rate and a constant concentration flows in the supply pipe L3 in a short time. At the same time, the ozone gas supply branch pipe L8 and the ozone gas injection branch pipe L5 connected to the supply pipe L3 and the syringe mounting adapter 6 connected to the ozone gas injection branch pipe L5 are also filled with the ozone gas of a predetermined concentration. Therefore, an operation of supplying ozone gas to the treatment instrument from the ozone gas supply branch pipe L8 to start ozone gas treatment, or an operation of attaching a syringe to the syringe mounting adapter 6 and injecting ozone gas into the syringe in a manner described later. I do.
[0030]
First, treatment for supplying ozone gas from the ozone gas supply branch pipe L8 will be described. When the display concentration of the ozone concentration meter 3 reaches a predetermined ozone concentration by the above-mentioned operation, the valve V5 of the ozone gas supply branch pipe L8 is opened, the valve V2 is closed, and the ozone gas supply branch pipe L8 is supplied with a predetermined concentration of ozone gas at a constant flow rate. To supply ozone gas treatment equipment. When the ozone gas treatment instrument is the ozone gas injection nozzle 40 shown in FIG. 9, an ozone gas conduit 41 connected to the ozone gas injection nozzle 40 is connected to the ozone gas supply branch pipe L8. Therefore, the ozone gas supplied from the ozone gas supply branch pipe L8 is supplied to the ozone gas injection nozzle 40 inserted into the body through the ozone gas conduit 41, and is injected into the body from the plurality of gas ejection holes 42 provided in the nozzle. The treatment is performed by squirting and exerting a predetermined action on the human body.
[0031]
When the ozone gas treatment instrument is the ozone bag 45 shown in FIG. 10, the ozone gas conduit 47 connected to the ozone gas bag 45 is connected to the ozone gas supply branch L8. Therefore, the ozone gas supplied from the ozone gas supply branch pipe L8 is supplied into the ozone bag 45 via the ozone gas conduit 47, and is used for treatment of infectious diseases, skin diseases, etc. occurring in affected parts (lower limbs in the figure) of the human body. Will be done. The ozone bag 45 may be a sealed resin film bag, but a plurality of minute holes are formed in the bag, and fresh ozone gas is released while releasing oxygen gas, which is a decomposition product of ozone, little by little. It is preferable that the ozone bag 45 be continuously supplied.
[0032]
Next, an operation of injecting ozone gas into the syringe through the syringe mounting adapter 6 (hereinafter simply referred to as “adapter”) provided in the ozone gas injection branch L5 will be described. 2 to 4 are cross-sectional views showing a first embodiment of the adapter. FIG. 2 shows an internal state of the adapter in a stopped state of the apparatus and a vacuum degassing state in a pipe by the vacuum pump 5, FIG. 3 shows an internal state of the adapter in a state where the ozone gas after vacuum degassing is filled in the pipe. FIG. 4 shows an ozone gas injection step of mounting a syringe on the adapter and injecting ozone gas into the syringe. It is sectional drawing which shows the relationship between the said adapter and a syringe in it.
[0033]
First, in FIG. 2, the adapter 6 is composed of a main body cylinder 10 and a movable valve member 11 urged forward by an elastic member 12 such as a compression coil spring therein. An opening 10c for mounting a syringe is formed, and a rear end portion has a threaded portion 10d attached to the tip of the ozone gas injection pipe L5. It is detachable. An annular seal member 16 such as an O-ring is disposed on the inner surface of the syringe mounting opening 10c.
[0034]
The movable valve member 11 includes a large-diameter portion 11a on the rear side (upper side in the drawing) and a small-diameter portion 11b on the front side (lower side in the drawing) integrally connected thereto. The rear surface 11a is pressed by the compression coil spring 12 and is constantly urged forward. When the apparatus is not operating, the plug 17 is inserted into the syringe mounting opening 10c formed at the distal end of the main body cylinder 10, and the outer peripheral surface of the plug 17 and the annular sealing member 16 are inserted. Is closely contacted with the atmosphere so that the inside of the adapter 6 is kept airtight.
[0035]
Further, a first gas passage 13 penetrating in the axial direction is formed in the rear large-diameter portion 11a, and a lateral hole 14a drilled from the circumferential direction toward the axial center is formed in the front small-diameter portion 11b. And a vertical hole 14b formed so as to open at the tip end portion in communication with the second gas passage 14. A first gas passage 14 and an ozone gas passage are formed as described later. It is what becomes. In a state where the device is not operating, since the closing plug 17 is inserted into the opening 10c for mounting a syringe, the distal end of the small diameter portion 11b of the movable valve member 11 is prevented from moving forward by the closing plug. The second gas passage 14 is in communication with the main body cylinder 10.
[0036]
In this state, when the deaeration operation in the pipe by the vacuum pump 5 described above is started, air remaining in the rear space 10a in the main body cylinder 10, oxygen gas used in the previous use, and the like are discharged from the pipe L3. The remaining gas in the front space 10 b of the main body cylinder 10 is exhausted through the first gas passage 13. Since the syringe mounting opening 10c is hermetically sealed by the annular sealing member 16 and the closing plug 17, outside air is prevented from flowing through the opening 10c.
[0037]
Next, ozone gas is supplied from the ozone cylinder 1 to the piping system, and when the piping system is filled with ozone gas, the plug 17 is withdrawn as shown in FIG. Then, the movable valve member 11 is pushed forward and moved by the urging force of the elastic member 12, and the front small-diameter portion 11 b protrudes into the syringe mounting opening 10 c and is closed by the annular seal member 16. The two gas passages 14 are closed, and the inside of the main body cylinder 10 and the outside air are still kept airtight.
[0038]
Next, as shown in FIG. 4, when the distal end nozzle portion 15c of the syringe 15 is inserted into the syringe mounting opening 10c against the urging force of the elastic member 12 in this state, the movable valve member 11 retreats. Then, the ozone gas injection branch pipe L5 and the supply pipe L3 communicate with the syringe 15. When the piston 15b of the syringe 15 is retracted in this state, the ozone gas is supplied to the rear space 10a of the main body cylinder 10, the first gas passage 13 formed in the large-diameter portion 11a of the movable valve member 11, and the front of the main cylinder. The gas is injected into the cylinder 15a of the syringe 15 from the tip nozzle portion 15c through the second gas passage 14 formed in the subspace 10b and the small diameter portion 11b of the movable valve member. It is also possible to automatically set the pressure of the ozone gas to flow into the syringe by the pressure of the ozone gas simply by inserting the tip nozzle 15c of the syringe 15 into the opening 10c. When a predetermined amount of ozone gas is injected into the syringe 15 and the syringe 15 is removed from the adapter 6, the movable valve member 11 is again pushed by the elastic member 12 and moves forward, and the state shown in FIG. The ozone gas in the adapter does not leak to the outside.
[0039]
Note that the ozone gas initially injected into the syringe 15 may contain unadjusted ozone gas supplied immediately after vacuum degassing, so that the first injection is released and the syringe is inserted again. Then, it is also possible to inject ozone gas. During this time, the ozone gas flows through the pipe, so that the remaining ozone gas not injected into the syringe is decomposed and made harmless by the ozone decomposer 4 and released into the atmosphere from the discharge pipe L4 as described above. It is.
[0040]
In the above embodiment, a compression coil spring is illustrated as the elastic member, but the present invention is not limited to this, and it goes without saying that a leaf spring, an air spring, or the like can be used. The annular seal member 16 also shows an example of an O-ring, but the present invention is not limited to this, and a soft V-packing or a U-packing can be used, and these V-packing and U-packing are used. In this case, it can be said that it is a preferable seal structure to form a multi-stage seal structure in which the arrangement direction is reversed so that sealing can be performed from inside and outside.
[0041]
5 to 7 are sectional views showing a second embodiment of the adapter. In the first embodiment, the movable valve member 11 is urged forward by an elastic member such as a compression spring. However, in the second embodiment, the valve member is made movable using the supply gas pressure of the ozone gas. 5 to 7 are cross-sectional views corresponding to FIGS. 2 to 4, and FIG. 5 shows an internal state of the adapter in a stopped state of the apparatus and a vacuum degassing state in a pipe by the vacuum pump 5. FIG. 6 shows an internal state of an adapter in which ozone gas after vacuum degassing is filled in a piping system, and FIG. 7 shows an ozone gas injection in which a syringe is mounted on the adapter and ozone gas is injected into the syringe. It is sectional drawing which shows the relationship between the said adapter and a syringe in a process.
[0042]
First, in FIG. 5, the adapter 6 is the same as the first embodiment in that the adapter 6 has a main body cylinder 10 and a movable valve member 11 movably disposed inside. An ozone gas passage 20 having one end opened near the inflow side of the ozone gas and the other end opened to the inner wall surface of the syringe mounting opening 10c is formed in the inside of the main body cylinder 10, and the front space 10b in the main body cylinder 10 The structure communicates with the atmosphere via the hole 22. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
[0043]
The movable valve member 11 has a large diameter portion 11a on the rear side (upper side in the drawing) and a small diameter portion 11b on the front side (lower side in the drawing) integrally formed with the rear portion 11a. Although the same as that of the first embodiment, in this example, an O-ring 21 is arranged on the outer peripheral surface of the large-diameter portion 11a, and thereby the inside of the main body cylinder 10 is divided into a rear space 10a and a front space 10b. And airtight between the two spaces. An O-ring 23 is disposed at the rear end side of the syringe mounting opening 10c to be in contact with and seal with the small diameter portion 11b. When the device is not operating, the plug 17 is inserted into the syringe mounting opening 10c, and the syringe mounting opening 10c is kept airtight to the atmosphere.
[0044]
In this state, when the deaeration operation in the pipe by the above-described vacuum pump 5 is started, the air remaining in the rear space 10a in the main body cylinder 10 and the gas passage 20 and the oxygen gas used in the previous use are removed. And the like are degassed through the ozone gas injection branch pipe L5 and the feed pipe L3, and into the front space 10b of the main body cylinder 10 through a communication hole 22 that penetrates the body of the cylinder 10 and communicates with the atmosphere. Flows, the rear space 10a of the movable valve member 11 is evacuated, but the front space 10b on the opposite side is maintained at the atmospheric pressure. To the pressed state. In this state, the opening position of the gas passage 20 is determined such that none of the openings of the ozone gas passage 20 communicate with the front space 10b of the main body cylinder 10.
[0045]
Next, ozone gas and oxygen gas are supplied from the ozone cylinder 1 and the oxygen cylinder 7 into the pipe, and after the pipe is filled with the ozone gas, the plug 17 is withdrawn. Therefore, as shown in FIG. 6, the movable valve member 11 is pushed by the pressure of the ozone gas and moves to the foremost end (the lowest end in the figure), and the tip of the small diameter portion 11b of the movable valve member 11 is moved. The portion protrudes into the annular sealing member 16. In this state, the lower end of the small diameter portion 11b is in contact with and seals with the annular seal member 16, and the upper end is sealed by the O-ring 23 disposed inside the opening 10c. The ozone gas flows into the ozone gas passage 20 from the rear space 10a of the main body cylinder 10. However, since the ozone gas passage 20 is configured to open between the

seal members

16 and 23, the ozone gas does not leak to the outside. Absent.
[0046]
Next, as shown in FIG. 7, when the distal end nozzle portion 15c of the syringe 15 is inserted into the syringe mounting opening 10c against the pressure of the ozone gas in this state, the movable valve member 11 retreats and the ozone gas The injection pipe L5 and the syringe 15 communicate with the rear space 10a via the ozone gas passage 20. When the piston 15b of the syringe 15 is retracted in this state, the ozone gas is injected into the cylinder 15a of the syringe 15 from the tip nozzle 15c through the rear space 10a of the main body cylinder 10 and the ozone gas passage 20. Become. When a predetermined amount of ozone gas is injected into the syringe 15 and the syringe 15 is removed from the adapter 6, the movable valve member 11 is again pushed by the gas pressure of the ozone gas and moves forward, and the state shown in FIG. Then, the ozone gas is sealed without leaking to the outside.
[0047]
Next, FIG. 8 is a sectional view of a main part showing another embodiment of the syringe connection adapter 6 used in the present invention. This embodiment has the simplest structure, in which a closing member 30 made of a soft elastic material such as silicon rubber is arranged so as to be in contact with the distal end portion 33 of the ozone gas injection branch pipe L5. 30 is provided with a fixed cap 31 for surrounding and pressing the peripheral portion of the base 30 with a pressing portion 34. The fixed cap 31 is configured to be screwed and fixed to the outer peripheral portion of the distal end of the ozone gas injection branch pipe L5. ing. An opening 32 is formed at the center of the fixed cap 31, and the closing member 30 is exposed at the opening 32. As described above, when the piping system is evacuated to a vacuum, the inside of the piping is isolated from the outside air by the closing member 30, so that the outside air does not flow into the piping. When a predetermined ozone gas is supplied into the pipe, the injection needle 18 of the syringe 15 is inserted into the closing member 30 to expose the distal end thereof to the branch pipe L5. In this state, the piston 15b of the syringe is retracted. Ozone gas is sucked and injected into the syringe 15. When a predetermined amount of ozone gas is injected, the injection needle 18 is withdrawn from the closing member 30 and is injected into a predetermined part of the patient as it is or by replacing it with an ultrafine injection needle.
[0048]
In this embodiment, since the closing member 30 is formed of a soft elastic material such as silicon rubber, the injection needle 18 can be easily inserted, and the closing member after the injection needle 18 is pulled out. Since the closing member 30 is formed of a soft elastic material, the through-hole formed in the pipe 30 is closed by a self-closing action, so that the ozone gas inside the pipe flows out and the outside air flows into the pipe. There is no. However, when used repeatedly, the through-holes formed by the injection needles are connected to form gradually larger holes, and the soft elastic material itself deteriorates, so it goes without saying that the soft elastic material is replaced at appropriate intervals. No. It can be easily understood from the drawings that the replacement is extremely easy.
[0049]
In the above description, the ozone gas injection branch pipe L5 and the ozone gas supply branch pipe L8 are arranged one by one in the main pipe. However, it is possible to arrange only one of them, a plurality of either, or a plurality of both. It is also possible to do. Also, the arrangement position on the main piping system is shown as an example provided on the downstream side of the ozone concentration meter 3, but this position is also on the downstream side of the place where the oxygen gas pipe L6 joins with the mixing pipe L2. If it is on the upstream side of the ozone decomposer 4, its mounting position is arbitrary.
[0050]
Further, in the example of FIG. 1, the inside of the pipe is evacuated by the vacuum pump 5, but this is mainly performed when the apparatus is left without operating the apparatus for a long time. Ozone gas remaining in the chamber is decomposed into oxygen and stays as oxygen gas, or the pipes are used for maintenance of the equipment (for example, replacement of ozone cylinders or oxygen cylinders, replacement of packings of pipe joints, etc.). The vacuum pump 5 is not necessarily required because the air flowing into the inside is used for shortening the purging operation (replacement of residual gas in the piping with a predetermined ozone gas) with the ozone gas after the operation of the apparatus is started. It is also possible to omit it.
[0051]
Further, in the example of FIG. 1, an example is shown in which ozone gas is diluted with oxygen gas supplied from the oxygen cylinder 7, but in the case of ozone gas for treatment of skin diseases shown in FIG. Unlike the injected ozone gas, strict control of the concentration of the ozone gas is not required. Therefore, a method using only the ozone cylinder 1 without diluting with the oxygen gas and controlling the concentration by the dilution is also possible. In order to obtain a medical ozone gas supply device, it is preferable that dilution with oxygen gas and concentration and flow rate management by the ozone concentration meter 3 and the control device 8 can be performed as shown in FIG. Not even.
[0052]
As described above, the present invention uses an ozone cylinder in which ozone gas is adsorbed and held by an adsorbent instead of a conventional ozonizer, and therefore, the ozone cylinder is required to have a long-term storage property of ozone gas. Therefore, an attenuation test using an ozone cylinder was performed, and the test contents and results are shown below.
[0053]
[Test Example 1]
After filling an ozone gas cylinder having a capacity of 10 L (liter) with ozone gas at 0.9 MPa, a change in ozone concentration when left at room temperature (25 ° C.) was measured. Table 1 shows the results.
[0054]

[0055]
Since the ozone concentration when injected into the human body is basically 20 μg / ml (about 0.93 vol.%), As is clear from the above test examples, even if the ozone cylinder is stored at room temperature, it is not less than one month. It turns out that there is no problem in the preservation of. The ozone concentration for the treatment of mastitis in cattle described above is preferably 1 to 50 mg / liter (0.05 to 2.3%) in Patent Document 2, and is used in the present invention. It will be appreciated that ozone cylinders can also be used to treat mastitis in such cattle.
[0056]
[Test Example 2]
The ozone cylinder is preferably stored at a low temperature. Therefore, the same ozone cylinder having a capacity of 10 L as used in Test Example 1 was filled with ozone gas at 0.9 MPa, and the change in ozone concentration when the ozone gas was maintained at 4 ° C. was measured. Table 2 shows the results.
[0057]

[0058]
As is clear from the above Test Example 2, when stored at 4 ° C., the decay rate of the ozone concentration after 4 weeks is only slightly less than 4%, which is lower than that in Test Example 1 in the case of storage at room temperature (less than 20%). It can be seen that it is significantly lower than that. In this sense, it can be said that the ozone cylinder is preferably stored at a low temperature. It goes without saying that this storage method does not depend on the frequency of use of the ozone cylinder, and when the ozone gas in the cylinder is used up in about 1 to 2 weeks, it can be said that there is not much difference between storage at normal temperature and storage at low temperature. If the frequency of use is low, low-temperature storage is recommended. In addition, as a method of storing the ozone cylinder at a low temperature, there is a method of storing it in a refrigerator, but when the apparatus is frequently used, the ozone cylinder is placed in a dedicated cooling container using a Peltier element. This is a simple and preferred measure.
[0059]
As described above, in the present invention, an ozone cylinder is used as an ozone gas source instead of a conventional ozonizer, and at the same time, an ozone gas treatment instrument such as an ozone gas pipe, an adapter for injecting ozone gas into a syringe, an ozone bag or an ozone gas injection nozzle. An ozone gas supply branch pipe for supplying ozone gas is provided, and various ozone gas treatment instruments are still used at present. Therefore, the present invention relates to an ozone bag or an ozone gas injection nozzle described in the above embodiment. It is needless to say that the present invention is not limited to the medical ozone gas supply device described above, and that various varie-shauns exist in the spirit of the invention described in the claims. Also, the structure of the adapter for mounting a syringe is not limited to that shown in the above-described embodiment, but may be variously modified, and the present invention is not limited to the above-described embodiment.
[0060]
【The invention's effect】
As described in detail above, according to the ozone gas injection device of the present invention, first, an ozone cylinder is used as an ozone gas supply source instead of a conventional ozonizer, so that an ozonizer is placed at a treatment site as in the past. There is no need to carry the apparatus, and it is possible to eliminate troubles caused by the apparatus such as a failure.
[0061]
In addition, it is difficult for doctors engaged in treatment at the site to maintain the ozonizer, and once a failure occurs, the ozone treatment must be interrupted, and the system lacks consideration for the patient. It is possible to greatly reduce the occurrence of troubles at medical sites because it is only necessary to manage the remaining amount of gas in the cylinders, such as oxygen cylinders and nitrogen cylinders used in ordinary medical sites without using This makes the device reliable for both doctors and patients.
[0062]
When using ozone gas by injecting it into a syringe, an adapter for mounting the syringe is attached to the ozone gas pipe, and the ozone gas is injected only by inserting the tip nozzle of the syringe into the adapter. Or simply insert the injection needle into the injection hole of the ozone gas pipe in the manner of inserting the injection needle into the medicine bottle and sucking the drug solution as is conventionally done in the medical field, By manually or manually pulling up the piston of the syringe, it becomes possible to inject a predetermined amount of ozone gas, so that the operation of injecting ozone gas into the syringe can be performed very easily.
[0063]
Furthermore, the adapter can be easily attached to the ozone gas pipe, and has a simple structure, so that it does not break down and can be used stably for a long period of time.
[0064]
In addition, if the ozone gas flow rate and the ozone gas concentration are of a structure that is always kept constant, a stable amount of ozone can be injected into the affected area at all times. The state in which the ozone concentration is unknown in the device is eliminated, and it is easy for a doctor or a patient to confirm the therapeutic effect.
[0065]
Also, in a treatment method using an ozone bag or an ozone gas injection nozzle, ozone gas can be supplied easily and stably, so that the ozone gas treatment has spread more widely and many medical institutions can easily perform the ozone treatment. It is expected to contribute to the maintenance and promotion of the health of the people.
